Fern Walters is one of Arthur's dog classmates. She enjoys reading poetry and novels (especially Sherlock Holmes and Frankenstein's Monster). She also writes her own poems and stories (Fernkenstein's Monster and The Trouble With Trophies). She is knowledgeable about computers, holds group poetry readings at the library, and is an amateur detective. Fern is usually a very shy and nervous person. Fern's mother, Doria Walters, is constantly trying to get Fern to become more extroverted. Even Fern herself sometimes worries she is "too quiet". She usually wears a purple long sleeved blouse with yellow collars and cuffs, yellow pants, and a red ribbon on her head. She's 8 years old.
